I would like to install a Faria water pressure gauge for a 2005 Honda 90 hp. Unfortunately I have not been able to find installation instructions so I'm asking for help from the experts. Is the installation as simple as T-ing into the "pisser" tubing or is there a place to tap into the water jacket? Thanks.
 
You will have to do a little tapping.

Remove the flush valve spacer (part #2) http://www.boats.net/parts/search/Honda/Outboard Engine/2005/BF90A5 LRTA/THERMOSTAT/parts.html

There is a round flat spot on it. It is about the 10 o'clock position on the curved portion. You should be able to see it easily before you take the spacer off.
Drill an 11/ 32 inch hole in the center of that flat area. Then thread it with a 1/8: NPT tap. That is where you will insert the nipple that usually comes with the Faria gauge.
